AlSi10Mg Alloy

 

AlSi10Mg is an aluminum alloy with excellent mechanical properties combined with low density, corrosion resistance and excellent castability while offering lightweight and flexible post-processing options.

Because it offers high strength, relatively high hardness and high thermal conductivity, it is used for parts which are subject to high loads.

Applications include housing and ductworks, engine parts, production tools and molds for both prototyping and manufacturing purposes.
